Android :: How To Obtain The Current Bitmap Of A Canvas

Nov 16, 2010

I want to get the current bitmap associated with my canvas so I can perform operations on it. I can't see how to do this though.

I've seen some examples where you create a bitmap and set the canvas to use this bitmap, so obviously you can then access it later, but I'm using the canvas returned from a SurfaceHolder so there's no constructor.

For instance, examples often show this kind of thing:


So at this point I can see bmp.

In my case, the canvas is obtained by:


So how can I get the bitmap for c?

In short, my aim is to capture the current canvas contents where I have drawn "stuff", and make a copy of it, reversed, to put underneath. Like a reflection. The example of this that I found performed it all via bitmaps, so I assumed I needed to somehow capture the current canvas to a bitmap to then use it.

Android :: Invert A Bitmap When Using Canvas.DrawBitmap?

May 14, 2010

I am starting to develop a game. Right now I got a sprite animation going when a player moves across using sprite sheet. In my sprite sheet the character is always facing the same way, left. Now if I want the character to move right, I want it to be facing right. So is there a quick way in android to invert the bitmap after it has been loaded in? Or do I have to create sprite sheet for character facing right?

General :: How To Reflect Horizontally On Canvas Image Bitmap

Sep 10, 2013

At canvas there are many methods (canvas.rotate (35); canvas.drawBitmap (myBitmap, x, y, null); and many other things), but the method of mirror reflexion of image is absent (or I have not found it). At Bitmap too not that is not. Is it possible to reflect horizontally on canvas the image given Bitmap?

Android :: Draw And Scale A Bitmap On A Canvas Using Bicubic Interpolation

Mar 25, 2010

I want to draw a bitmap on a canvas with bigger size than it is. I can use canvas.drawBitmap(bitmap, null, destRect, null); but that gives a poor quality, as the result is pixelated, if the source image is sightly smaller than the destination rectangle. How can i draw my bitmap using bilinear or bicubic resampling?

Nov 16, 2010

I want to get an animated text in Android where it should run from left to right on the screen.

Eg: I want to get this text. private static final String QUOTE = "Nobody uses Java anymore. It's this big heavyweight ball and chain.";

Android :: Do Animation When Click On A Bitmap?

Feb 24, 2010

I have bitmap displayed on the top of the screen when the app is started up. When clicking on the bitmap, the image should move to the bottom of the screen.

I have read the AnimateDrawables from ApiDemos, but the animation is done on a Drawable Object. If it can use on bitmap, it will be great!

Here is my code...

Just starting a little game project and have a super basic question. what's the best way to store animation images for a game? I looked at the alien bloodbath code and they store multiple frames in a single png file. Is that the preferred way or is there easier/better way to do it? MP4?

Android :: Problem Using Runnable - Handler.postDelayed For Bitmap Marker Animation

Jul 26, 2010

I want to place an animated marker showing a user's current location in an Overlay over a MapActivity. I need to be able to turn the animation on and off.

I thought this could be accomplished as follows:


The constructor is invoked from the main MapActivity.onResume() using

locationOverlay = MyLocationOverlay(this)

And the animate/draw is invoked by


However, the run() method never seems to be invoked.

Android :: Rotate Bitmap With Canvas.rotate

Sep 24, 2010

As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!

HTC Hero :: Myster Icon / Yellow Sheet Of Paper With Dog-ear

Oct 16, 2009

Hope this isn't a repeated noob question. I searched through the forum and couldn't find this topic.I have this mysterious icon on the HTC Hero's task/status bar. It showed up on the 2nd or 3rd day after getting the phone. It looks like a yellow sheet of paper with a dog-ear in the bottom-left corner. I had installed a couple of notepad apps and uninstalled all except for one called Note Me. I've checked Task Manager and it doesn't appear to be running. Deleted all notes in Note Me, checked its options, and the author's web page doesn't show this icon.Pocket your world - Home of software solutions for your iphone, gPhone and Blackberry Anyone recognize this icon? It's left of center in the attached photo. I drew a red arrow pointing to it.

General :: Android Tablet As Sheet Music Viewer?

Feb 8, 2011

I have ordered a Zenithink ZT-180-102A and plan to use it to view sheet music for the band I play in, and turn the pages with a USB foot switch that sends a PgDn key to Acrobat Reader.

I would think that the tablet will be (just) big enough to view A4 PDF sheet music at 10.1" (would have preferred slightly bigger).I'm hoping Adobe Acrobat Reader for Android can go full screen and respond to PgDn messages.Battery life seems a bit light, but figure I can run it from the power adapter if required.how well the screen would work in sunlight.If I'm reading the foot switch description right, I can configure the key press via the software on a Windows machine, then plug it directly into the Zenithink as a standard HID device.

Android :: J2ME Like Sprite

Sep 25, 2009

For my useless project of the month I'm working on a 'emulator' to run J2ME programs on Android. But now I'm stuck with the J2ME Sprite implementation. Specifically the transformations used in it.

In my Sprite I have a bitmap with three character images. I would like to paint the second frame mirrored or rotated 90 degrees. What would be the best way for it?

I have following code that paints the given frame without any transformations.

frameX, frameY are frame position coordinates on give sprite bitmap.

Rect src = new Rect(frameX, frameY, frameX + spriteWidth, frameY + spriteHeight);
Rect dst = new Rect(paintX, paintY, paintX + spriteWidth, paintY + spriteHeight);
canvas.drawBitmap(image, src, dst, null);

As I understand I need to make some matrix magic on the canvas, but I have not been able to figure this out.

Android : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory

Jul 21, 2010

I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.

Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);

Any help would be great?

Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It

Apr 2, 2009

I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it

I am doing it as follows and it works on the emulator.

On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.


What I am asking:

a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it

b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?

In my app, resolution is not an issue. If it works better for small photos that would be fine.

Android :: Point Sprite Support

Oct 5, 2009

Can someone confirm for me that point sprites are not currently supported in Android? Calling gl.glEnable(GL11.GL_POINT_SPRITE_OES) is triggering a GL_INVALID_ENUM error, so I assume this is the case, but I'd appreciate a confirmation before I proceed with an alternate design.

Android : How To Color Key 2d Sprite Backgound

Mar 19, 2009

I am working on a 2d library for creating a game including sprite collisions, sorting and animation converting (.spr to Java classes/ bmp's).

At first I used png's with the background color being transparant (24 bits png image) but I want to use 256 color bitmaps with the background color being transparant.

Is this possible to do color keying in android? I looked at several other threads about this topic but the all ended without a solution.

Also I am now using the canvas.drawBitmap to render my sprites, but will using opengl be faster?

HTC Incredible :: Micro USB Side Of Cable In Sprite

May 29, 2010

I knocked a cup of Sprite onto the floor and it dumped out right over the micro-USB end of my charger (as in all of it was emerged in Sprite). So it's been a few days and I know it's completely dry, but I was wondering or not if it would be okay to still use it? I didn't know if that somehow messed the cable connector up. Luckily I still have the charger for my old BlackBerry Storm.

HTC Droid Eris :: Restore Files Using Sprite Mechanic

Mar 13, 2010

After following Matlock's post about upgrading to 2.1 I tried to restore all of my files using Sprite Mechanic. (Going back and re-reading his post he says that it doesn't work in 2.1-DOH). After installing Astro I tried re-installing Sprite Mechanic from the backup folder that I made with Sprite Mechanic thinking that was the way to get all of the back-up apps out of the back-up folder and onto the phone. I started Sprite Mechanic and proceeded to push the "Restore" tab and it brought up a list of all backed-up apps. I scrolled through them, deciding which ones I really wanted back and which ones I could do without, and then pushed the "Restore" button. Well, my phone froze up and would only display the status bar across the top. I tried pushing different buttons, but to no avail....
